eBay - 2x Batteries $13 shipped.

Found this deal while searching for a deal on batteries for the Fuze. Haven't bought them, usually skeptical about eBay items, especially from China. Figured I'd post a thread with it so if anyone would like to purchase at a low price. States that they're both 1340mAh. If they both work as expected it'd be a great price, but again still skeptical about buying from a Chinese eBayer.

eBay Seller name: otakugarden

I'm a sucker for a good deal, I took the bait. If/when I get them in I'll report back.

The only deal with that ebay seller for the same thing was for 18.88 total, which is still dirt cheap. So, I took the bait as well. Will report back if no one else does, or if I have a conflicting opinion.

it seems to me fake... i mean it's too cheap

I bought this back in early November, except then it was 2 batteries plus a standalone charger for about $20. They've all worked very well to date.

Blah I took the bait! Toooo cheap not too hmhmh
Kewlj1313

I bought one!
Hope they actually send me two working batteries and it's not some deceptive ad.

I saw this sellers offers on Ebay. I didn't pull the trigger as the last battery I purchased on ebay for my Tilt was a complete rip-off. As they say "if it's too good to be true, then it probably is".
Please let us know your experiences with this seller/batteries.

let me know how this goes, my battery already seems to lose juice quickly

I bit too, hopefully it's not bad.

I also bought the 2 batteries and charger for $20 like Lulugirl. All seem to work well. My only problem is that my Touch Pro doesn't recognise the battery level in the new batteries. So when I put in one of the new batteries, the battery meter on my device shows 0% battery. It still works though. I just use it until the phone turns itself off because of a low battery. Seems to last about as long as the stock OEM battery, but I'd of course prefer to have a warning as to how much battery life I have left.
Lolugirl (or anyone else), have you had this problem? If so, were you able to fix it?
All in all though, they were cheap enough that I am still happy with my purchase, especially since my usage drains the battery in less than a day.

That's proof that these batteries are fake.

I got the batteries after 2 weeks finally! They both have the same serial number and part number. But the serial and part numbers are different from the factory battery.
I noticed sticker on the battery is less clear than the factory battery I originally had. I will try it out later on my Fuze when I have the time.

I bought the same battery package as lulugirl896 (two generic batteries + standalone charger). They work fine, no problems whatsoever. The reason these batteries are cheap is because they are not OEM (HTC) batteries, but generic no-brand batteries. Since the labels are just copied, the serial numbers on all of these batteries are identical (13XA188P003454).
They are working fine in the original UK Touch Pro and Fuze (pretty much the same capacity as the OEM battery). However people who have CDMA Raphaels (Sprint/Verizon) have been having problems like juttonn described (always shows 0%, or "Battery not recognized").

The battery power seems jumpy. It was at 97% before I shut the power off for the night, then when I turned it on in the morning it was down to around 60%? I ran it for 8 hours on airline mode (the screen was on though), now it's down to 34%. I'll try it for another few days and report back.

Same here! just got mine yesterday, definitely a fake less clear label with the same serial number hmhm! Haven't tried mine yet either, maybe tonight hopefully they don't kersplode or anything!

Initial tests seem good!
When I first put this battery in straight out of the package it showed up in TBattery as FULL(mAh): 900, but after letting it charge once and then run all the way down and now as you can see from this screen shot it has charged back up again, it is showing the full 1340 mAh so thats good!
This battery lasted all day yesterday in my phone! I am very satisfied, but as stated above it is obviously a fake, the HTC label is a bit blurry and the serial is the same on both batts, but oh well! seems to work well!

Glad to know! But the percentage I see is wrong most of the time. So I just switch batteries every day. My charger has a light to determine if the battery is fully charged or not.
Can anyone confirm that Tbattery fixes the problem with the fake battery? I am am a bit afraid of trying it out since I haven't even hard-spl my device yet and I know it's not an ordinary program.

mine arrived last week and have used both through 3 power cycles and they appear to do drain much quicker than my oem battery. Where do you get TBattery to test? Google doesn't seem to come up with anything.
nevermind: found it. mine says 1340mAh but these batteries definitely drain faster than the OEM. Hopefully after a few more powercycles they will begin to last a little longer. If not, they were still worth the ridiculously low price.

I noticed after the 2nd and 3rd cycle the battery indicator is more accurate now and not jumping around. I also noticed the same, where they do drain faster than the stock OEM battery.

[Q] extended battery

Hi
i've just received an extended battery (cheap non htc) from ebay for my HD2. But since I placed my order I've heard that some nand roms don't work correctly with this type of battery.
Anybody know what type of problem I might run into with an extended battery, which roms definately don't work with an extended battery and if there are any fixes for the roms that don't work with one?

The only non-working batteries with Android are the HTC original 2300 ones.
Every other battery works fine with NAND.
And I got one of those expensive HTC things....

Confirming this is true for the OP as I do use the 2400mA from Ebay (got it for $13) on NAND, also used it with all SD builds, Non-EB and EB based.

Really? Wow, so you dont notice any issues with overheating when charging or not being able to charge to 100% in the phone?
What sort of battery life do you get? Should be like 35-40hrs right?
I have an ebay 2600mah that I got for $13 which seems awesome but I've only run it in the phone for a short period so far. It even has the back cover with a kickstand. I had to wait a month for it to get here from Singapore and it just got here yesterday.
I've switched to NAND ROMs now but at one point I had an SD build that I was getting 20+hrs battery life out of. I havent really had he chance to fully evaluate the battery life with my NAND builds but so far it looks to be not as good....

I just bought one..ships from Hong Kong..prolly have to wait ~ 3 wks for it arrive.

ive been looking into buying an extended battery recently.
im running android 2.2 nand.
so i wont have any problems with any extended battery?
2400mah? 2600mah?

The word out there is that aftermarket extended batteries - like the 2400mAh work well with NAND. I forked out $10.00 USD, what the hey..they've all gotten decent reviews, and work with NAND.

60% better than the stock is what I get, depending on how I use it, I CAN go 2 days easily.
I don't have any heat issues, it gets warm but nothing that seems different than with the stock.
I got the same as you, just 2400mA, comes with the cover and the kickstand, the cover is cheap plastic and pops off easy, it's not a durable and nice as the stock back and the kickstand broke after like 3 uses but oh well, a $13 battery with 60%+ battery life is fine with me.
Keep in mind, when you get your EB, it WILL drain from 100% to 0% and turn off (same as the stock battery) however, when it dies you just take the battery out and put it back in then reboot and it'll have ~60-65% remaining.
In my opinion, NAND and SD have the same battery life, NAND ahead a little bit because it doesn't spike as frequently.

Well worth the money =P
--- All of this is based off of hands-on experience, I use the 2400mA Ebay Battery with the cover and kickstand and have been since Late September.

Yeah I bought the cheap one with the kickstand, only took 11 days to reach the UK from hong kong.
No issues so far other than it seemed to drain really quickly from 100% to 79% in about 2 hours with no usage, its been okay from 79% though, dunno if it needed a long 1st charge.

I got the same issues with the HTC extended battery.
Charging / usage is reported wring by NAND kernels, worked OK tho with Hastarin's kernel. On MDJ's kernel it will even shut down at boot-up.
With SD builds when I plug in the phone it shows up as charging extremely fast then after unplugging charge falls also extremely fast to about 70-60% and then drains normally.
Offering as tester if anyone has any idea or beta NAND kernel that might fix this.
By the way in WinMo it charges perfectly and drainage is excellent/normal as advertised, so it's not a battery issue but a kernel support issue.

Hey, thanks very much for your reply. It is much appreciated.
I'm using the EB now. The back door for it seems lightweight but I cut a hole in the back of a protective case I have for my phone and the whole thing now feels pretty solid.

Just wanted to report back. I have the $13 Singapore 2600 mah battery and it works with MDJ Cyanogenmod 7 v2.6.
I dont even have to remove and replace the battery for it to work. It's not perfect though, it basically runs down normally (slightly faster than I would like) and lasts a full day getting down to a 15% charge. Then it stays at 15% for another entire day and then discharges normally from there.
With all the progress that has been made on Android for HD2, I feel optimistic that the last several minor bugs will eventually be worked out and the device should function flawlessly.

Yeah I get exactly the same with the cheap EB, dont need to remove the battery but it runs down fairly quickly to 15% then stays at 15% for ages. I have tried a variety of roms both nand & CWM, they all give similar results. Obiously the battery isn't running down very quickly at all, rather it's the way its level is being reported by the OS.

Amazing battery life on epic

I thought i would share this information because I've wasted so much time and effort trying to find the best bettery/performance combination. What I have finally conceded to was the fact that i needed an extra battery. I've read opinions that charging externally will give extra battery life, and let me tell you, they are all true.
So as of right now, under normal use and conditions, my battery is sitting at 89% charge with 7h 39m of on/standby time.
Here's the formula that works best for my epic:
Rom-baked snack
Kernel- bakedsnack step 2
Charge battery on external charger
Use ultimate juice defender to cycle data on every 15 min when screen is off and cconnect when on.
Thats it in a nutshell. The extra OEM battery and charger cost me like 30 bucks on amazon. Make sure its OEM battery because most after market batteries wont charge unless you throw it on the external charger only, which could leave you in a jam if you only have power cord.

I've been debating about doing somthing this, but with my work, I need the "instant" email. I was in Staples, and they had a 2000mah external USB battery for $18 clearance. It comes with a cable and many tips for it and a little pouch to put them all in. I bought 2. I'm usually in range of a power supply, but then I've got 2x2000 mah extras just in case. I know I lose some because of the way charging works, but it's keeps me going for a very long time.

I'm running Baked Snack with Extreme kernel overclocked and I get excellent battery life, would be even better if I could just kick my internet addiction.

I get 30 hours on my G2 running cyanogenmod clocked at 1.3ghz. muahhaha

30 hours is crap that's what I get on leaked froyo which is terrible I was getting 60+ hours on 2.1

60??? Holy heck, I thought 15 hours with my Epic 4g running on my Yoobao 2800mAh battery was impressive... This is with no battery tweaks, no performance tweaks, just plain old stock rom. I usually leave wifi/4g/gps on all the time and get about 10 hours on my extended battery.

I have several extended batteries n get 15 to 30hrs
Plain stock 2.1

Sigh! wow, i gotta do this.

For ppl that get 60 hours and such, thats because ur barely using the phone! I get like 8 to 15 hours depending on how much i use it. I used to use juice defender but i get similar battery life with and without it so i dont think it does that much saving.

Not talking about having the phone sit next to your bed all day unused. I get 30 hours with moderate usage consistently, and on the Epic running the battery saving kernels/ROMs can't do that.
You sir, are the crap that you speak of.

He didn't say 30 hours like you said. He said 60. And if you to get 60 its cause you don't ever use your phone. I don't care what setup you have if you use your phone you will not get 60 hours on stock battery.

There's really no such thing as "not using" these phones. He's either lying/exaggerating or he's disabled everything that makes this not just a flip phone, and never uses it even for that.

what i have observed is... sitting idle....without any activity nt even screen on.. after unplugging from a 100% charged state.. reduces to 80% in a cpl of hrs.. i m on viperrom frozen and havent used any battery calibrating apps yet.

[Galaxy K Zoom] Extended Battery

Hello Folks!!!!
I have ordered this item....i'm waiting for its arrival!!!!!!
http://www.aliexpress.com/snapshot/6195359693.html
in the meanwhile, i found this second battery:
http://www.alibaba.com/product-detail/Lowest-Price-of-Samsung-Galaxy-K_1976591285.html
and finally, the king of battery manufacturers:
http://mugen.co/mugen-power-4400mah...-samsung-galaxy-k-zoom-with-battery-door.html
when available, i'll order the mugen battery!

I've tested the "2850mAh High Capacity Battery" in the first link.
my suggestion is: DO NOT buy this battery.
this battery will charge faster than the original one but will drain very fast...faster than original!
in about six hours i used 30-40% of the extended battery power....whereas i spent about 20% using original battery.
the quality did not satisfy me.
now i'm testing mugen 4400 battery...results in a few days!
cheers!

Thanks for your advice. Very interested in the results of the experiment... the original one last for little few hours.
Some questions:
In Mugen page i cant see the weight of the 4000mAh battery. How much does it weights?
With the "new" cover, it seems that tje flash is a bit "covered". Does it flash correctly?
Thanks again!

shortly i'll post the weight of the product!
i can confirm it can flash correctly!

as a last step (and detached post), i will show some photos of the 2850mah Aliexpress battery i bought....currently i'm disappointed with this.

Hi!
i can add some words about 4400 Mugen battery life.
i'll add some screenshot of my KZoom. i made two kind of test: medium use (so a type of normal-medium stress) and heavy use (hard stress for smartphone).
MEDIUM USE
in the medium test i use my telephone like this:
in backgroung Whatsapp, Telegram, Viber, Skype, Cerberus
gps always active
wifi always active
data always active
2 or 3 photos
a few minutes of internet browsing
a few minutes of calls (audio calls, not video calls)
a few minutes of Google Maps
HEAVY USE
in the heavy test i use my telephone like this:
in backgroung Whatsapp, Telegram, Viber, Skype, Cerberus
gps always active
wifi always active
data always active
10-15 photos
about 15-20 minutes of internet browsing
about 20-30 minutes of calls (audio calls, not video calls)
a few minutes (maybe 5 minutes) of Google Maps
some update made by Google play or Samsung market on wifi
Today i made a further test: using smartphone as a camera.
in this use:
in backgroung Whatsapp, Telegram, Viber, Skype, Cerberus
gps always active
wifi always active
data always active
about 40 photos (made in about 4 hours); these are the results!
these are two photos, like an example:

Hi, Livio, Thanks for ur review,

Hi!
i tested these covers!
i bought them when i was on "stock" battery. None of them will fit the Mugen battery, even if strong forced.
No way, even with no Mugen cover!
i can add that according to my opinion, using a case with this battery will make the smartphone too much wide and large.

Thanks

No way, even with no Mugen cover!
i can add that according to my opinion, using a case with this battery will make the smartphone too much wide and large.

I've tested the "2850mAh High Capacity Battery" in the first link.
my suggestion is: DO NOT buy this battery.
this battery will charge faster than the original one but will drain very fast...faster than original!
in about six hours i used 30-40% of the extended battery power....whereas i spent about 20% using original battery.
the quality did not satisfy me.
now i'm testing mugen 4400 battery...results in a few days!
cheers!

The mugen is interesting, its weight will probably mean as heavy as with autopop but was it not possible to find an original spare battery to use ?
or do you find battery life of original just too short to live with.

as a last step (and detached post), i will show some photos of the 2850mah Aliexpress battery i bought....currently i'm disappointed with this.
I can only share the same experience - these batteries does NOT perform up to specified mAh !! at best it is slightly under the stoch batt !!
-ALSO-
NFC does not work with 2850mAh batteries !?!?? I don't know why ??

Livio, fantastico review.
I have the official Samsung spare battery and portable charger.
I got almost the same capacity, but I still must carry them on a pocket, bag, etc.
The Mugen is a good option to increase the battery capacity in a single package.

Replacing the battery on the Axon 7

Anyone know where i can get the battery replaced on the Axon 7 in the UK? My battery drains too quickly and does not last a day. Ive looked at the videos on Youtube and it looks tricky to replace the battery. I love my Axon 7 especially the front facing speakers.

I replaced mine a few days ago. It's one of the easiest battery replacements I've ever done. It's very easy. Just make sure you have the proper tools

If you look up in Amazon as I can not post the link:
"Cameron Sino 3100mAh Li-Polymer Replacement Battery for ZTE Axon 7"
Just be careful when disconnecting the ribbons and carefully removing the battery from the screen as mine took a lot of finesse and some heat to pry it loose. I now have a great battery but now have no home and back button after attempting to repair many times. Luckily there is an app you can use to at least make my phone usable again.

how did you break those? The ribbon for the buttons is on the other side of the frame... are you sure your screen ribbon is well connected?
Have you tried pushing on the screen roughly where the volume buttons are located, to see if it gets reseated? It's weird that the screen works but it might be just that

I took the phone apart 4 times ensuring the ribbons were well connected hoping that may have been the culprit. Also took the battery out each time, applied pressure all around the screen which makes me think I might have shorted out something. Strange though the right button still works, just the home and back button not functioning.

And this, folks, is exactly why you shouldn't be dissasembling phones unless you're very skilled with with electronics repair. You forget to connect a cable or w/e, then post here with complaints. I'm not physically well coordinated, my hands lack the fine motor skills and dexterity to work with small parts. If I have electronics hardware I need worked on, I take them to a friend's shop and he does the work for a small fee. I get everything back knowing the job is done right.

Hi Karl,
I have pretty basic electronic skills, and I found the battery replacement pretty easy.
There are plenty of guides on youtube, and as long as you have a decent toolkit--spudger, flat metal pry tool, correct sized bits--it should be an easy thing to do.
One step to watch out for is at the beginning; you need a hair dryer/heat gun to loosen the plastic bezels at the top/bottom of the front face. Be careful applying too much heat. My top bezel has a small bend divot from where it got too soft and bent when I removed it.
Just go slow and take your time; I think my take apart and reassembly was just over 30 minutes.
Good luck!

Are you sure that the battery is really the reason?
When I switched to the last LOS 15.1 ROM a few month ago, I noticed a rapid decrease of battery time.
And also the latest version of the imgur-app drains the battery extremely - if active, the battery only lasts for about 4 hours.
(I constantly force-quit it to get over half a day)

that's the kernel, it's probably not too optimized - but it's not necessarily the only reason! If you set up a decent ROM with a good kernel like one of Kran's EAS kernels and still get bad battery life, then you can bet it's the battery (you still don't need to - run Accubattery, let it log for about 3 days, then check the capacity estimate).
I honestly don't know or care about the persist stuff because I've gone through roughly the same ROMs than these guys here and have no such trouble. But I won't deny it
Btw if you get a fast discharge of a couple % after disconnecting the phone or your phone shuts down unexpectedly at 10/20/30%, those are telltale signs of battery degradation.

Introducing too many variables can confuse the issue.
I've been on the same rom since 9/2017 - RR 14.x based. I used to go 2 days between charges, now it's 1 day. Usage hasn't change all that much. I have a battery on order. I'd also like to update to 15.1. Goal is not to do any upgrading until at least a week or two after installing the new battery. Otherwise, existing SoT and battery usage numbers will have little value.
Of course, it's a good idea to perform a backup (twrp/titaniuam) for anyone replacing the battery just in case something goes wrong along the way and your phone turns into a brick.

Latest LOS 15.1 Unofficial fix this for me. Maybe dev make better the kernel now.

Hello,
Speaker grills can be bought on Ali... easily so no problem at all for battery replacement BTW. you can buy original ZTE battery on Ali too.

You think there's much difference between an oem and third party battery? I'm only two charges in on the cameron sino, but still showing about 2700 mAh with accubattery. Tempted to get one of those usb amp meters to see what it's really taking in.

So far 3 full charges (1-2% to 100%). Accubattery still showing ~2650-2700 mAh capacity.
Actual use seems to be restored. Note the pic below.

point is, there is pretty much no way to know whether the battery you are buying is original or not. many bought the original looking ones and they have the font slightly off, knockoff-like... Which doesn't matter anyways because they perform just as good (or bad?) as a new OEM battery.

well, you could claim a bad battery if that's the case. 2700 mAh is just dead

Past use wasn't quite the same. I'd typically recharge around 40% (to 100%). Getting to 40% would take less than a day. So there's definitely more life to it. Going 2 days between charges would be satisfactory.
I'll give it another full cycle to see how it's doing. Not sure another battery would make a significant difference. Seller might offer an exchange but is it really worth the hassle.........

you don't get it entirely. If that battery really has 2700 mAh, its capacity is about to fall off a cliff, and your phone will start having early shutdowns whenever you give it any load. that's pretty much how it works with lithium, it is advised to change the battery when it is at 80% capacity since it'll start behaving like crap in no time
Our batteries probably have a newer/better chemistry than those on the picture (they are charged at 4.4V), but the concept is the same.

Accubattery indicated ~2000/2100 mAh for the old battery. In terms of actual use I'd be at ~30% by the end of the day with my typical use. Phone never shut down/rebooted. I don't play games or run cpu benchmarks. Probably the most intensive activity would be creating twrp backups with compression, titaniumbackups, playing youtube (hd), or running speed tests (symmetrical gigabit network). We'll see how the phone works after a month. This was an ebay/paypal transaction so there's 180 days to make any sort of claim on it. It's a $16 battery - If I'm able to go two days between charges like I used to, I'll be a happy camper regardless what the app says. I do have one of those KEWEISI amp meters on order so it'll be interesting how that compares to the app.

that's weird. if anything i can tell you i had lots of shutdowns when my battery was at 2500 mAh, and people around here are using batteries around the same capacity with the same problems.
But it's possible that you just don't abuse it that much, I'm talking about 100% CPU usage, for example taking an HDR+ enhanced pic with GCam (CPU pegged, 10+ pictures snapped in a second). there was no way to do that with less than 30% battery, it shut down immediately.
still, i guess you saw the graph. Please tell me how it goes with the charge counter, it might just be that Accubattery is off by ~400 mAh and that's why you didn't get nearly as much trouble with the older battery.
